FFICE FELIX DELIT, OF BRUSSELS, BELGIUM EJECTION MECHANISM FOR SPORTING GUNS Application filed September 29, 1927, Serial No. 222,848, and. in Belgium October 12, 1926.

The present invention relates to a sporting gun provided with ejection mechanism provided with an ejector which is constantly urged to effect the ejection by a spring and released by a tumbler moved at the end of the oscillating movement.

According to the invention the notch of the ejector upon which the tumbler acts is situated in such a manner as to enable the ejector to move a short distance before the ejection in such a manner as to effect the separation of the sleeve.

This movement may be effected positively by the action of a portion of the oscillatory member on the stem of the ejector. The tumble-r is moved through the medium of a pin with which it is provided and which engages with a suitable groove in the oscillatory membelt.

The accompanying drawing illustrates by way of example one form of construction of the invention, the separate parts being slightly separated from their assembled position and having portions broken away so as to facilitate the explanation of the operation.

The barrel 6 is applied in the usual manner upon the oscillatory member 7; the assemblage is completed by means of the forepart which is formed in two parts. One of these parts 2 completes the oscillating hinge, the other 4 is capable of being secured to the first part and extends along the barrel.

The part 2 of the hinge is provided with a supporting face 1 which, after assemblage, comes into contact with a projection 8 secured to the barrel and to which is transmitted the efiort exerted, after the oscillatory movement, to the said part 2 of the hinge.

The contact faces of the elements 1 and 3 are inclined in such a manner that the resultant of the efforts exerted on the member 2, after the oscillatory movement, passes to the interior of these faces in a direction which is substantially normal thereto.

As shown in the drawing the part 2 of the hinge is composed of a block provided on one of its faces with a cylindrical concavity and on its opposite face with a projection provided with the supporting face 1 above referred to.

The assemblage of the said block with the front of the wood may be effected by means of a screw 8 carried by the said block and screwing into a nut located in the wood.

For efi'ecting the assemblage of the forepart with the barrel use is made of a member 4 provided with the usual assembling bolt not shown in the drawing. This member is secured to the block 2 by means of a pin which engages in the holes 9 provided on flanges 10 of the said member 4 and in a hole 11 of the projection provided on the contact face 1. It is also secured to the wood by means of screws.

The member 4 which embraces the said projection and which extends along the barrel is provided with an aperture 5 for the passage of the projection 3 secured to the barrel.

. he ejection mechanism is provided with j an ejector 12 constantly urged to effect the ejection by a spring 13 surrounding the stem of the ejector 12 which extends up to 14 as hereinafter described.

The tumbler 15 pivotally mounted on the pivot 16 is constantly urged into the engaging position by a spring 17. The engagement is effected by a notch 18 provided on the stem of the ejector 12. This notch is situated in such a manner as to enable the ejector to move a short distance before the ejection in such a manner as to permit the starting of the ejection. For this purpose a certain amount of free movement is provided between the tip of the tumbler and the said notch when the members occupy the closed position as is shown in the drawing.

For the purpose of effecting the separation in the case where the tension of the ejection spring 13 is not sufficient to produce this, the stem 12 of the ejector is provided with an extension let which, after the oscillatory movement, engages against a face 19 provided on the frame 7 adjacent the axis of the hinge 20. v After the separation has been effected the tip 5 of the tumbler is in contact with the notch 18 of the ejector 12. If the oscillatory movement is continued for a slight amount the notch 15 will soon be separated from its engaging position and the ejector is released,

which enables the ejection to be effected under the action of the spring 14.

The operation of the tumbler 15 is obtained by means of a pin 21 with which it is provided and which engages with a groove 22, 23 of the oscillatory member 7. This groove is provided with a part 22 directed at right angles to the axis of the barrel, which part enables the introduction of the pin to be effected, when assembling and its removal when disassembling, and which is followed by a part 23.

parallel to the axis of the barrel and directed towards the axis of the hinge 20. The part 23 serves to effect the driving of the pin 21 when the barrel is oscillated.

The stock, not shown in the drawing, is connected'tothe oscillatory member which is not provided with a tail, by means of a screw passing longitudinally through the stock and screwingintoa nut 24 which is fitted at the rear part of the oscillatory memher 7 in a suitable groove 25 preventing relative movements between the nut 24 and the oscillatory member 7. It will be understood that the said nut may be replaced by any other suitable securing system.

The closing mechanism which does not form part of the invention is not illustrated in the drawing. There is however shown the seatings 26 provided in the oscillatory memher 7 for the passage of the aXis of the closing key.

What I claim is:

A breakdown gun comprising a frame having a fixed hinged pintle, a barrel having a hinged lug abutting against said hinge pintle, an. ejector provided with a notch, carried by said barrel, a spring for actuating said ejector, the latter being provided; with an extension adapted normally to abut against a cooperating face on said frame, in combination with a tumbler positioned to engage the ejector notch after the movement of the ejec tor for a short distance responsive to oscillation of the said frame, said: tumbler being 0perativel-y connected to said frame 'by a pm projecting demountably into a suitably shaped cam groove into said frame.

In testimony whereof I have affixed my signature.

FELIX DELU..
